Lately I've been noticing more tram-lining with my S2K. (a dartyness and tendency to follow ruts and wear grooves in the road)

Four things are different:

1. Spoon X-Brace
2. Mugen Sway Bar
3. Very worn front tires, newish rear tires
4. 38 psi f&r

Any idea which of these might be causing the recent increase? How much tram-lining do you experience on your S2K's?

When my A032Rs wore down I got ALOT of tram lining. I thought the alignment was shot until I realized the new tires cured that.

I always run 39psi, tyres are well worn and due for replacement imminently - no x-brace, no sway bar and never a hint of tramlining. I'd say 1 or 2.

#4 I have had the same prob since increasing tire pressure. I am going to lower it back to spec and see if it helps

Utah S2K

The S2K is already plenty stiff. The X-Brace and sway bars are great for the track.....but the street? Honda pays its engineers a lot and Honda spends a lot on R&D....it amazes me that people spend so much on "accessories" which usually detract from street performance which is how the S2K was targeted. My personel favorite is guys that go to +3 tires on the street.......
No tram problems here, stock Honda engineering all the way.....

Utah, I'm sure pfb would like to thank you for all your help

My guess is #3 based on experience with other cars (sorry no first hand probs w/ S2000) but #4 is so easy to rule out you ought to do some experimenting.

BTW, my S2000 does it the least out of the cars I currently drive on a regular basis.

All of the above. Stiffness increases responsiveness (right, like it's a feature) to road imperfections. Old tires reduce resistance to road imperfections.
